The DENSADEG — A New High Performance Settling Tank
Great compactness: high settling velocity.
Excellent treated water quality: use of lamellae.
Production of concentrated sludge: simultaneous sludge thickening.
The DENSADEG is a new compact clarifier-thickener capable of meeting all these requirements. It fits into the line of sludge recirculation type lamellae settling tanks using chemical reagents. The original design of the reactor induces both a highly dense and homogeneous floc and settling velocities ranging from 20 to 40 m/h. In addition to settling, sludge thickening takes place in the DENSADEG (30 to 500 g/l); the thickened sludge can then be directly handled by a dewatering unit. More than fifty DENSADEG are presently in operation around the world in many areas of applications: drinking water, urban wastewater, sludge treatment, industrial water and storm water treatment.
An example is discussed in drinking water (Morsang-sur-Seine) and in urban wastewater (Gréoux-les-Bains).
